Do they still work in the winter? I’m moving to Shetland and would like solar panels but I’ve read they are harmful to the environment (to make and after 20-30 years of use/end of their life)
Yes, they do still work in winter, but production is much lower. Mine went live on the day before the winter solstice, but still provided 20% of the electricity I used in January, and in May/June/July they are expected to produce more than I can use.
There are websites which can help you work out prospective production…. You’re about as far north as you can get in the UK, whereas I’m in Devon. The difference in production from otherwise identical systems would be significant, but you’d need to get some estimates to see if it is still worthwhile.
I confess I didn’t look into the environmental impact of making/disposing of them. Any more than I looked into the environmental impact of gas and coal powered power stations, but I’m sure they have one.
Is there planned obsolescence with solar panels?
I don’t know about planned, but they don’t last for ever. Typical life expectancy is 25 years for panels, 10-15 for the inverter (the bit that converts the DC output of the panels into 240V 50Hz AC and syncs it to the grid.)
But then, nothing lasts for ever.
